What is the correct term for energy converted from motion due to friction?

• A. Kinetic energy
• B. Thermal energy
• C. Potential energy
• D. Chemical energy

Answer: (B)

The correct term for energy converted from motion due to friction is thermal energy. When objects move and come into contact with each other, the motion creates friction, which generates heat. This heat is a form of energy known as thermal energy. Friction converts the mechanical energy (from motion) into thermal energy, increasing the temperature of the materials involved.

Kinetic energy refers specifically to the energy of motion itself, while potential energy is stored energy based on an object's position or condition. Chemical energy pertains to energy stored in the bonds of chemical compounds. Understanding these distinctions highlights why thermal energy is the appropriate term in the context of energy conversion due to friction.
